I started with a really (and I mean REALLY) old tube top of mine.
I used one of her shirts as a pattern for the tank top, cutting the arm hole angles the same as the sleeveless top I was copying.
Sew the front and back pieces together at the side seams. The half moon shapes that you are left with will be your sleeves.
Sew a small seam on the raw edge of the arm pit holes. Then sew a small seam on the raw edge of each of the sleeves then attach them to the front and back of the top. And you are done!
The top was so easy to make mostly because I used the bottom existing hem and the top existing hem. But I really like this style on my daughter's body type so I am going to make a couple more from regular fabric using this top as a pattern.
Hope you all are having a great summer so far!
